Test Wiki:Suppressors

The suppress user right grants the ability to do an enhanced form of revision deletion called suppression by ticking "Apply these restrictions to Sysops and lock this interface" which hides the revision from admins as well as other users, and produces a log message in the private suppression log instead of the public deletion log which only other suppressors and Stewards can see.

Additionally, suppression can be used to hide a username that is grossly inappropriate from Special:ListUsers at the same time as indefinitely blocking them. This feature will also suppress the username from most logs and edits, although the username may still be visible in some places, such as rollback edit summaries.

This right is automatically granted to Stewards and System Administrators who can assign it to themselves, but Non-Steward suppressors may be appointed by community consensus, or by Steward delegation of authority with a consensus at least 2 Stewards supporting. Suppression is usually only used to remove personal information, copyright infringement, serious personal attacks, or other grossly insulting material, but there might be exceptions at their discretion. This is one of the six default MediaWiki user groups, see mw:Help:User rights and groups.
